Abstract

PCT No. PCT/DK92/00291 Sec. 371 Date Mar. 22, 1994 Sec. 102(e) Date Mar. 22, 1994 PCT Filed Oct. 1, 1992 PCT Pub. No. WO93/07089 PCT Pub. Date Apr. 15, 1993A method of controlling a wastewater purification plant comprises the steps of measuring two or more of a number of parameters, automatically controlling the plant on the basis of the measurement values obtained using a mathematical model for the purification process, evaluating the quality of the measurement value for at least one parameter on the basis of a comparison of the said value with an expected, dynamic value interval calculated continuously on the basis of said mathematical model and a simultaneous and/or a previous measurement of one or several other parameters and/or a previous measurement of the same parameter, and controlling the plant on the basis of the quality evaluated measurement values.
